Liver spots or age spots are flat and usually brown spots on the skin, but you may hear some people calling these skin changes solar lentigines. They usually appear on the areas of the skin frequently exposed to the sunlight, especially on the face, arms, shoulders and the hands. Although people suffering from this problem are commonly over 40 years of age, solar lentigines can be seen in much younger people as well.How to Recognize Liver Spots?

Age spots can be prevented only by limiting exposure to the sunlight. Don’t expose your skin to the sun between 10am and 4pm. The sun is the most intense during this part of the day, so try not to be outside at that time. Wear the broad-brimmed hat to protect from sunlight and make sure to be in tightly woven clothes when on the sun. Cover your arms and legs with this clothing and you probably won’t have (at least) any new liver spots.
Use broad spectrum sunscreens, with at least 15 and up to 50 UPF (ultraviolet protection factor). These sunscreens will protect you from UVA and UVB sunlight, so make sure to apply them 15 to 30 minutes before going outdoors.
